选择定语从句的关系词，重点注意从句谓语动词与先行词的关系。

这里，先行词是a sport ,从句谓语动词是climbs,所以，它们的关系 （在运动中攀登），即 climb (a mountain )in the

sport ,即就是，动词和地点状语的关系。因此，要选用关系副词where ,也可以转换成(介词加关系代词)，即 in which .

类似高考题

Long-distance running is a sport

where /in which a runner needs more than much strength to cross the

finishing line .
